Big update:
I'm confused about how everything got fixed. Just after cleaning my PC again, I unplugged all the cables from my PSU once more and plugged them back in except for the CPU cable which was stuck tightly. Then I put the GPU in a different PCIe slot, tested my RAM sticks one by one and found nothing wrong. After that, I cleared and restarted a Windows update that was stuck at 0 (still stuck at 0 even now) and opened Monster Hunter World. Suddenly everything worked perfectly—even Ghost of Tsushima. I'm not sure which steps actually made a difference.
If it's this way, maybe the PSU cable connectors were the problem or the PCIe slot was damaged.
A few connections didn’t work as intended. Replacing or reattaching them probably helped restore a proper connection.
This is not unusual.
Still, it’s wise to spend time regularly backing up vital information.
This should always be part of the routine—just in case.
OK so I swapped in my 5060 Ti and my PC successfully passed the 3D Adaptive and VRAM checks for the GPU, plus the PSU power test on OCCT. So far everything seems to work, but I'll continue testing with different games and will share the results later.

Tried some graphically demanding tasks in Monster Hunter World for roughly two weeks and everything is functioning properly now. The issue was identified as being related to the GPU.
